In 18 games since his return, Zimmerman is hitting .313 with two home runs and 12 RBI, along with a .421 on-base percentage.

Zimmerman was hitting just .226 with one home run in 15 games prior to his injury. He has raised his average for the season to .274. 

Lavarnway went 1 for 7 in two games while reserve catcher David Ross was on the 7-day concussion disabled list. Ross's return Friday means Lavarnway heads back to the minors.

According to the Atlanta Journal-Constitution, Gattis leads rookies in extra-base hits (20), home runs, RBI (27) and slugging percentage (.587), while ranking second in on-base plus slugging percentage (.895).

Gattis has started just one of the team's last five games, despite hitting three home runs in that span. 

Ross has been out since May 11. He will return to a backup role behind Jarrod Saltalamacchia. He's hitting .209/.320/.512 in 43 at-bats, including four home runs.

The Reds placed Sean Marshall on the 15-day disabled list to make room for Parra on the active roster. 

Although Hunter's season line is still a sharp .313/.360/.412, he has been slumping for a bit over a month. His OPS peaked at 1.048 on April 19, and since then he's hitting just .252/.310/.304. The 37-year-old has had just two days off in that span, so maybe the Tigers hope another will give him a nice reboot heading into the weekend.

Romero has begun a throwing program, but has yet to take the mound again. Prior to the injury, he posted a 2.84 ERA for Triple-A Syracuse, but has a 9.00 ERA in 12 innings in the majors last year. 

Danks will be making his season debut after spending most of the first two months rehabilitating from a shoulder injury. He managed a 3.18 ERA through 22 2/3 innings of rehab starts, including a 3.45 ERA in three starts at Triple-A Charlotte.

Bray, who was battling for a roster spot in spring training, has an opt-out clause in his minor-league contract by June 1, and it is not clear whether he will choose to stay with the team.
